A requestHandler works as an URL that can have predefined parameters. By default you will be querying the /select/ requestHandler. It, for instance, predefines the default number of rows to return (10) and returns all fields of a document (*).
<requestHandler name="standard" class="solr.SearchHandler" default="true"> <!-- default values for query parameters --> <lst name="defaults"> <str name="echoParams">explicit</str> <!-- <int name="rows">10</int> <str name="fl">*</str> <str name="version">2.1</str> --> </lst> </requestHandler> But you can also define more complex requestHandlers. The default configuration adds the dismax requestHandler (/dismax/) but it's actually the same as the default requestHandler if you would define all those configured parameters in your URL. So by defining the parameters in the solrconfig.xml, you won't need to pass them in you query. You can of course override predefined parameters with the exception of parameters defined inside an invariants block. Check the documentation [1] on this subject but i would suggest you study the shipped solrconfig.xml [2] configuration file, it offers better explanation of the subject.
